Description
[technical field]
The present invention relates to a kind of vibration insulation structure, especially relate to a kind of vibration insulation structure of light fixture of specialty.
[background technology]
The lighting that is installed on various industrial environments generally all needs to bear vibration source in environment, for the industrial environment light fixture, comprise the light fixture that military project requires, typical shock and vibration acceleration range is generally all between 5G to 10G, environment light fixture peculiar to vessel must stand more harsh requirement, has brief acceleration even to reach 100G.
Therefore, for solving the antivibration life problems of big-and-middle-sized light fixture, the antivibration life problems of especially searchlighting searching class light fixture, under the prerequisite that little amplitude is gained in weight, existing big-and-middle-sized lamp vibration isolator is generally to adopt to install the method vibration isolation such as rubber blanket or rubber shock absorber additional at present, and employing air spring (being rubber air spring, Air suspension) is also arranged, stimulating frequency is during lower than the intrinsic frequency of vibrating isolation system, and vibration isolator does not play the vibration isolation effect; When stimulating frequency and intrinsic frequency were close, vibration will be amplified, only have when stimulating frequency be greater than intrinsic frequency times the time, vibration isolator just has vibration isolating effect, usually requires stimulating frequency to be greater than 2～3 times of intrinsic frequency, in order to obtain good vibration isolating effect.
Rubber shock absorber is generally used for being cut, pressurized or situation about hobbing, and still, uses for a long time the rubber can be aging, and, under heavy duty, particularly, when high temperature, has larger creep, so should not be subjected to the continuous deformation of large load.
Because rubber shock absorber rigidity is excessive, the vibrating isolation system intrinsic frequency is higher, only radio-frequency component is worked, inoperative to intermediate frequency and low-frequency component, has amplified on the contrary excitation.So, in order to improve the vibration isolation ability, not only will make the amplitude-frequency spectrum of vibrating isolation system as far as possible low, more to pay attention to especially reducing the amplitude versus frequency characte of low-frequency range, so just must make the fundamental frequency of vibrating isolation system as far as possible low, response speed must be very fast simultaneously.
The characteristic of rubber blanket is similar with rubber shock absorber, but the volume decrement when the pressurized is minimum due to rubber blanket, only in the time laterally protruding, could compress, thus usually make sketch plate to allow horizontal protrusion and to be subjected to deflection, to increase static deflection.
Above-mentioned rubber-type vibration isolator, be highly suitable for isolated low-frequency excitation input, but because there is the long-term ageing problem in rubber, therefore this vibration isolation way reliability is poor.
Another kind is steel-wire isolator, it is for the vibration isolation of strong shock and vibration for the broad band low frequency random vibration, test and theory analysis show that the nonlinear isolation device has very good effect for suppressing the broad band low frequency excitation, steel wire rope vibration isolation dish is a kind of nonlinear isolation device, but its weight is large, complex structure, and cost is higher, cost is generally more than 10 times of spring-like assembly, is more than 20 times of damper of ultra-high tension, therefore is difficult in enormous quantities for special lamp.
And select general linear vibration isolator, and meet the requirement of isolation frequency ratio, the rigidity of vibration isolator is just less, the quiet distortion meeting of system is larger, make vibration isolator device stability step-down, the damping of vibration isolator is also generally linear simultaneously, not necessarily adapts to the requirement of broad band low frequency random vibration vibration isolation.If the vibration isolation transmission efficiency reaches 0.2, just mean that vibration isolator cut down 80% amplitude.If incoming frequency reaches or near the intrinsic frequency of light fixture, carry-over factor is greater than 1, this means that vibration has been exaggerated.So lower intrinsic frequency is adopted in the vibration insulation structure designing requirement of light fixture, to avoid driving frequency (20Hz～100Hz).
In sum, in the illumination field, special lamp will be continued equally, strong vibrational excitation, and is generally three-way vibration.Yet as mentioned above, existing big-and-middle-sized lamp vibration isolator can not meet this requirement.
That is to say, also do not have at present supporting lamp vibration isolator that light fixture and excitation vibration source are isolated fully, special lamp is in order to obtain at a distance accurately light projector angle in middle high-intensity oscillation occasion, just must use the less carbon steel support of thickness below 6mm of rigidity, but thinner support often is difficult to bear the lamp holder quality more than 10 kilograms, after exceeding the working strength of support, very easily cause the fracture failure of support.
Therefore, special lamp is needed the support vibration insulation structure of three-dimensional vibration isolation badly, and special lamp can be used on heavy support.
